Description

Golf swing training device

The present invention relates to a golf swing training device for effectively reinforcing the muscle strength necessary for a golf swing and developing a correct swing posture during golf practice.

Golf enthusiasts usually do not hesitate to reduce the number of golf clubs, even a little bit, and focus on swing practice or ball strikes. In addition, they are still standing in the heart of the golf course to make progress as much as possible. Furthermore, in order to increase the flight distance of the ball, although efforts have been made to purchase expensive clubs, etc., the flight distance is often inconsistent with the desired effect.

Under such circumstances, in recent years, a golf swing image training device (for example, refer to Patent Document 1) has been available. Alternatively, there is a golf swing exercise device for learning an ideal posture from preparation before swing to completion after swing (for example, refer to Patent Document 2).

Further, as a training device for actively increasing the muscle strength at the time of golf swing, there has been a training device for strengthening a muscle strength having a rotational load device, which fixes a grip at a rotary load device, which is a grip system. One end of the flexible stainless steel spiral bar is pivotally connected with a gripper, and the grip of the grip is rotated from the rear swing to the striking state of the hitting ball (for example, refer to the patent) Document 3).

Furthermore, in a swing exercise machine having a grip connected to the intermediate arm and secondly coupled to the rotary arm, there is an exercise machine in which the grip is placed from the state of the back swing to the lowest position of the hitting position. When the lower arm is rotated to rotate the turning arm, the resistance in the turning control device is caused to be high due to the resistance of the operating oil (for example, refer to Patent Document 4).

In the exercise machine for the purpose of improving the muscle strength of the golf swing, there are devices for miniaturizers or large devices, or complicated structures, etc., but any one of the devices is used to enhance muscle strength. The load is constant, and the load cannot be adjusted according to the personal difference of physical strength.

In the golf-related field, an image training device for a golfer's golf swing, a swing exercise machine, or a muscle strength training device for a golf swing has been published. Among these, although it seems that the muscle strength of the golf swing can be actively enhanced, the stress of these devices against the golf swing is constant; in addition, within the range of the golf swing track, It is also impossible to adjust the range of the stress that balances the individual's muscle strength, or how much the stress is.

Moreover, of course, as the muscle strength of the golf swing increases and further muscle strength is to be established, the industry lacks appropriate devices to meet its objectives.

Also, hold the grip into the back swing, lower the rod from the upper end position, and then hit the ball, then in the middle of the movement from the homeopathic movement to the completion, within the range of the arc-shaped trajectory depicted by the grip, if it can be expected A variety of areas that actively enhance the muscle strength necessary for the body can result in more satisfactory results for the reinforcement of the golf swing.

Especially when performing a golf swing, training to maintain the correct swing plane of the club head is very helpful for improving the flight distance, but almost no satisfactory device has been found.

Or, if there is a suitable swing for a small swing (such as a light shot that is indispensable in hitting a hole), the two wrists ideally move correctly in a small angle range with a pendulum type, and It can be used as a device for training the swing trajectory, which is more satisfactory.

In order to solve the above problems, the present invention is constituted by the following mechanisms.

That is, a golf swing training device is configured to hold the rotation of the arc in a circular shape while holding the grip of the golf swing mechanism, and transmit the shaft through the power of the lock of the inherent swing arm holder. The weight arm holder to which the weight arm is fixed is transmitted around the rotation of its axis, and the weight of the weight arm functions as an effective load for cultivating the swing force (claim 1).

Locked.

Further, in another example shown in FIG. 4, a power axle box 11-1 is attached to the front end of the bracket 5, and the base end of the power transmission shaft 12-1 on the outer side of the power axle box 11-1 is interposed. The swing arm holder 8 is coupled to a golf swing mechanism 7 including a swing arm 10. Further, at the other end of the power transmission shaft 12-1 on the outer side of the power axle housing 11-1, a weight arm 18 is attached via the weight arm holder 17, and at the front end of the weight arm 18, FIG. 5 The weight 19 shown in Fig. 6 is slid to a preferred position, and a male thread 21 is formed in a long range so that it can be locked by the upper and lower nuts 20.

On the other hand, the golf swing mechanism 7 basically includes: a swing arm 10 fixed to the swing arm holder 8, a slide arm 9 slid via the slide member 22, and further a connection piece 23 on the slide arm 9 The grip 24 is fixedly moved. Further, the configuration may be such that the grip 24 is rotatable around the grip shaft in a special case, and the angle α of the grip shaft and the connecting piece 23 can be appropriately moved in the front-rear direction. In order to rotate the grip 24 about the grip shaft, or to move the angle α by an appropriate amount, a universal joint method can be employed. Here, the grip 24 need not be attached to the upper side with respect to the connecting piece 23, and may be attached downward from the connecting piece 23.

Further, the sliding member 22 is mainly a linear movement system which is in the longitudinal direction of a rail composed of a rectangular cross section, and is caused to slide the slider via a ball bearing or a roller bearing, or a double cylindrical outer cylinder in the longitudinal direction. The slider may also be a method of sliding the length of the swing arm 10 via a wheel-shaped drum, not by a bearing method, etc. In short, as long as there is a swing trajectory corresponding to the grip 24, the grip 24 The distance from the swing arm holder 8 can smoothly follow the mechanism.

In Fig. 5(a), since the drawing surface is complicated, the sliding member 22 is not described, but the spring pin 27 fixed to the swing arm 10 and the spring pin 27 fixed to the sliding arm 9 are provided by the mounting. The spring 28 of the weight of the sliding arm 9 causes the sliding arm 9 to smoothly slide via the sliding member 22. Further, by weighting the weight of the slide arm 9, the mounting of the spring pin 27 and the spring 28 can be omitted.

Furthermore, it is shown in FIG. 5(a) that the sliding arm 9 integrated with the variable stopper 30 can be moved to narrow or only within the range of the set position of the slide positioning slider 29. The range of travel of the grip 24 is somewhat enlarged to facilitate repeated practice, for example, by moving the slide positioning slider 29 to a position indicated by a broken line, the sliding range can be enlarged or vice versa.

As described above, by setting the slide positioning slider 29 and the variable stopper 30, the operation of the club of the pendulum method of the putter practice can be repeatedly experienced. Further, the slide positioning slider 29 or the variable stopper 30 is not indispensable, and can be removed in order to simplify the golf swing mechanism.

[Examples]

Hereinafter, the golf swing training device of the present invention will be specifically described.

First, the user of the device of the present invention can adjust the forward tilt angle of the bracket by the angle variable arm 6 according to the physique of the device, and adjust the grip by adjusting the foot pad 4 up and down. Put the height position of 24. Next, while holding the grip 24 for the golf swing, the grip 24 draws an arc-shaped movement centering on the axis of the swing arm holding member 8, and the sliding arm 9 is interposed, for example, in the sliding member 22. The linear movement system 22 smoothly enters and exits in the axial direction in the longitudinal direction, and the arcuate movement of the grip 24 is transmitted to the swing arm 10 via the sliding member 22, and the swing arm 10 is fixed to the power transmission. The swing arm holder 8 at the base end of the shaft 12 is transmitted as a rotational force centering on the power transmission shaft 12.

In the example of FIG. 3, the arcuate movement of the grip 24 causes the power gear 13 assembled to the other end of the power transmission shaft 12 to rotate, and is transmitted to form a corresponding gear ratio with the power gear 13. The interlocking gear 14 rotates in the reverse direction. For example, more specifically, if the gear ratio of the power gear 13 and the interlocking gear 14 is 1:2, the grip 24 is rotated between 3 and 9 o'clock of the clock. When rotated by 180 degrees, the interlocking gear 14 is rotated by 90 degrees. In this manner, the gears having different gear ratios of the power gear 13 and the interlocking gear 14 are prepared in advance as setting materials, and the gear ratio is changed as needed, whereby the rotation angle of the interlocking gear 14 can be curved with respect to the grip 24 The rotation track is variously changed.

Here, the rotation transmitted to the interlocking gear 14 is transmitted as the rotation of the weight arm holder 17 fixed to the power linkage shaft 15 around the axis of the power linkage shaft 15 on the outer side of the power shaft housing 11, and further This acts as a stress that rotates the weight 19 near the front end of the weight arm 18 of the weight arm holder 17 about the axis of the power linkage shaft 15.

On the other hand, in the example of Fig. 4, when the grip 24 of the golf swing mechanism 7 is held for the golf swing, the rotation of the grip 24 in an arc shape is transmitted from the golf swing mechanism 7 to the lock. The power transmission shaft 12-1 of the same shaft of the swing arm holder 8 of the swing arm 10 and the weight arm holder 17 of the fixed weight arm 18 are converted into a power transmission shaft 12 for the weight arm 18 The axis of the -1 is the stress of the center rotation. Further, the mounting angle of the swing arm 10 fixed to the swing arm holder 8 and the weight arm 18 fixed to the weight arm holding member 17 with respect to the power transmission shaft 12-1 is preferably slightly different. Specifically, when the grip 24 is displayed at the position of 3 o'clock, the weight 19 of the weight arm 18 is assembled in the direction of 5 o'clock, and the attachment angle can be adjusted according to the preference.

The weight 19 of the weight arm 18 can be locked to the weight arm 18 by the maximum stress by locking the front end of the weight arm 18 even in the case of, for example, a counterweight 19. Near the center, that is, the shorter the interval between the weight arm holding member 17 and the weight 19, the smaller the stress of the weight 19 is. Further, of course, by gradually increasing the number of the weights 19 and shifting the locking position of the weight 19 toward the front end of the weight arm 18, the stress of the weight 19 can be further increased.

The weight of the weight 19 locked to the weight arm 18 and the weight 19 caused by the locking position, that is, the load against the golf swing, can be selected as the load corresponding to the muscle strength of the user. Moreover, as the muscle strength increases, the load can also be increased. Also, muscle strength training can be performed on any part of the body, for example, a load that is only suitable for training the left hand of the guiding hand, or a load that is only suitable for the swing of the right hand.

More specifically, in the case of the right swing, in the arc-shaped trajectory depicted by the grip, in order to eliminate the range of the load force against the swing force, the arm 18 can be assembled by the weight arm holding member 17 group. The setting of the weight 19 of the weight arm 18 in the dial of the clock is, for example, an angular position from a position exceeding 12 o'clock to 6 o'clock.

Moreover, although the mounting angle of the weight arm holding member 17 can be installed in any range of 360 degrees, the swing arm holding member can be freely installed within a range of 360 degrees by fixing the mounting angle of the weight arm holding member 17 in advance. The mounting angle of 8 can also set the range of stress from the weight 19 to the desired position.

Furthermore, if the front end of the extending direction of the weight arm 18 of the locking weight 19 exceeds 12 points in the dial of the clock, it is preferable because the weight of the weight 19 falls under the influence of gravity. A rotation stopper (not shown) of the weight arm 18 is attached so as not to exceed 12 points.
